I have a paxton supercharger on my 300. I have ngk plugs. Gapped at.30. I took it out and got on it. Soon as it get above 4000 rpm. Its starts poping. Now i have notice on my fuel pressure it set at 6 psi. When i floor it it went down to 4 psi. My friend tells me i need a boost regulater. And that i am leaning out the motor. So please help so i can get it to run great. Thanks
